Answer:
The correct answer is increases by $10,000 per year
Step-by-step explanation:
Given:
contribution margin in the department= $50,000 per year
Fixed expenses charged to the department = $65,000 per year
Now,
Current net income = Contribution - Fixed expenses
or
Current net income = $50000 - $65000 = -$15000 (negative sign depicts loss)
Also,
Fixed cost = $65000 - $40000 = $25,000
Thus,
If this department is discontinued, the loss of $15000 would be eliminated.
but the fixed cost will be there
The net operating income would decrease by
= $25000 - $15000
= $10,000
Hence, the correct answer is increases by $10,000 per year
